VS 2010 Displaying Information During Drag Event?
Jan 27, 2011
I have a form set up for drag and drop. The dragging and dropping is working nicely, as it allows the user to put a pair of dots onto a rectangle, which is exactly what it is supposed to do. However, I would like to give them some information about where they are dropping the points. My first thought was that I could use a tooltip. However, it appears that tooltips are not displayed during drag events. The tooltip works well, and is showing what I want, once I have released the mouse button, but not before then. The only other alternative I can think of, and it is not a very appealing alternative, is that I have some labels elsewhere on the form to display the information.

I started programming in VB many moons ago, but I put it down about a year ago. I picked back up a project I was working on a few years ago and Visual Studio 2008 Pro had to convert it. It seemed to work just fine but I wanted to make it "look .NETish", so I simply copied all the controls and code into a new project.The new project won't display information stored in static arrays on a Rich Text Box. The arrays are declared public in a code.vb file and the array is populated in the load event for the main form.I've tried inserting a "test" button to see if I could somehow get it to display trying a few different things. Essentially:
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click
Dim test As String = Gems(0)
[code].....
Has array conventions changed or something in the past year or so? How do I extract the information contained in Gems() that I have so maticulously entered so long ago

I am working on a Windows Forms Application and I have got stuck and wondered if anyone can provide some much needed direction. [Code] The user makes a selection of, say region, and then a DB layer sends back some linq IQueriable(of sometype) for a particular month. I wanted to add a month column each time they select a month.
I can't seem to do this too well with a datagridview, I have tried making a class that holds the measure as string and value as decimal and then create a list of these to bind but then if I add a new one I have problems as it just overwrits the origional one. I could just place a series of textboxes and fill them as I go but this seems like it is a problem waiting to happen kind of way. What I really need is some sort of grid that is expandable.

I remember using a one liner, something along the lines of AxWindowsMediaPlayer.currentMedia.Artist or something similar, that required no complex processing of the file, to display artist, album and song title. Using the WMP 11 control. It's been a while since i needed to use that and i've lost it.
Was wondering if anyone knew what that was, and if im mistaken, what easy method, without processing strings, files etc. there is in getting ID3 tags.
Im using Visual Basic Express 2008

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.

I have been coding an application for a LeaderBoard for a game. I have all the Login sorted using Mysql and even have all the Account infomation displaying in lables etc. for account info form. Now I am trying to UPDATE information and this is how I was trying to do this...
Dim UpdateInfo As New MySqlDataAdapter
Dim mycommand As New MySqlCommand()
Dim mydata As MySqlDataReader
Dim query = "UPDATE Login SET Pword = '" + UpdateTxtBox.Text + "' WHERE Uname = " + Login.Uname
mycommand.Connection = conn
mycommand.CommandText = query
UpdateInfo.SelectCommand = mycommand
mydata = mycommand.ExecuteReader()
But comes back with an Error saying... Unknown column 'username here' in 'where clause'. Now the username is in the database as I have just logged in with it and I am taking it I have the Query wrong somewhere.

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

Is there any way to keep it draging even after changing the ShowInTaskbar state.

I need to display images when I press a key on the keyboard. I have a form with a textbox and a label on it. When I type a letter in the textbox it appears on the label. I got that part to work. But now I want to display a image in the label when I press a key on the keyboard. I have found some images on the internet that I want to display when I press a key on the keyboard. For example when I type the letter A in the textbox instead of A appearing I want an image of an apple to appear, or if I type the letter B a banana would appear, or if I type the letter D a dog would appear. I have been searching on how to this I came across the keyboard event such as the keypress event. Can I use a keypress event of the textbox to do this. Can I assign a certain image to a certain key on the keyboard, and have that image display whenever I press that key.

I am using Excel 2007, VS2008 Pro.I am building a VSTO Add-in that requires "drag and drop from Excel cells to a drag-enabled task pane".So far I notice that I can only drag and drop within the cells themselves. It does not allow me to drop into the task Pane or drag past the sheet limits.(http:)[url]...
Note: The task pane has drag drop enabled, I ahve already tested I can drag/drop from task pane to excel but I need to do this the other way around?

I had a user ask me today if I could make it so they could simply drag and drop text from other programs into the app I've written. I found an old (2002 & 2003) article on drag and drop, but I'm sure things have been made better since then.
Anyone doing this today can point me in the right direction? Is this much of a pain to enable?

I am dragging a control over a different control as part of a drag/drop operation. AllowDrop is set for both the dragged control and the drop target. There is a DragDrop handler for the drop target, but when I drop on the target, the handler is never called, and nothing happens. I expect that I am overlooking something simple, but, as might be expected, I can't see it.
When I drag onto a different type of control, it is working correctly, and dragging to the control in question was once working correctly, but not anymore. I did make a bunch of changes, but the fundamental issue is that the dragdrop event is never raised for the control that is the drop target.

I have a picturebox that has a semi-complex image on it and also has a series of other pictureboxes, most of which are set to not visible. The way the program works, the user can click and drag a couple different items on the parent picturebox. The things they can drag are not actual controls, but parts of the image itself. That is all working fine. While testing, I had all of the subordinate pictureboxes (there are a variable number of them) visible showing a black background. I have now improved their implementation, so I changed the display so that only the subordinate pictureboxes that actually have something in them are visible. For all the others, they have .Visible = False.
The problem is that when I click and drag on one of the items in the parent picturebox, all the invisible pictureboxes become visible. They have no image in them, so they take on the color of the backgroud behind the parent picturebox. This is undesirable. I want the invisible pictureboxes to remain invisible during the drag and drop action. The one solution that seems promising is to set the image of all those pictureboxes to some transparent image such that, though they are visible, they will not appear as anything. A bit of testing shows that this technique would work.
